Very easy to install to an existing bilge pump. We typically will update the float switch every couple of years.

This switch was original equipment in my shower sump and in the 5 years I've owned this boat I've replaced the switch 3 times. The switch works for a short period of time and then will not activate when the water level rises above the float. Slight upward pressure activates the switch but the leverage from the float is insufficient to make the contact. I'm currently looking for something that does NOT have mechanical contacts. Lets hear it for the good-old-days of mercury switches

      Comments about Attwood Automatic Float Switch:

      Replaced this item on boat twice in past 10 yrs. Appears this product does not last >3 yrs with frequent use. Hence purchased the extended warranty after it failed first time. Only reason I'm sticking with it is that it's the only float switch that will fit in the sump box.

            Comments about Attwood Automatic Float Switch:

            This is the second float switch i had fail in the past year. I go to my boat thats on the lift and the boat is full of water from the last rain storm. And being in florida we always have rain storms most afternoons/evening. So i have to locate a better made float switch that wont fail on me.. I would look elsewhere if you are relying on a float switch to keep your boat from sinking.

                    I had an Attwood switch that leaked shortly after purchasing it brand new.

                    When I went to fix it, I found that Attwood made it impossible to service or repair.

                    I was highly disappointed, and over 1000nm from the nearest shore at the time. It failed when I needed it the most.

                    You can read my full review and see photos of the inner workings of this switch in the 'reviews' section of SailorRob.com

                        In a shower sump. I replace the float every year or two. The float will be completely under water and it will not turn on the pump. By very lightly manually lifting the float the switch then will click and it works, for 1 cycle. The float works fine but after time the switch gets harder to press. Definately has a switch design issue. All 7 or 8 I have replaced have had the same problem in about a year..

                          The product is in an A/C water sump. Custom fitting requires replacement with exact duplicate. Durability less than one season. Fails to turn on and empty sump even after constant cleaning and maintanance. Have replaced five switches in five years.
